there was a proposal many (*many*) years ago from jesse chappell that
fully covered looping with JACK. it was never implemented. as it
stands, it is not possible to get seamless looping with jack
transport. in practice it might sound right for a given user with a
given set of clients, but change any aspect of the configuration and
it would no longer be seamless.
